GLYT2-positive neurons of the VRG. Shown are Neurobiotin-labeled E-DEC neurons of the rostral VRG (a1, arrow) and the caudal VRG (b1, arrow). Both neurons are GLYT2-positive (a2 and b2, respectively). The neuron a1 was located ventromedially to the cluster of ChAT-active motoneurons (a3, arrowhead). b3, Examples of the axonal branching and terminal boutons in the caudal VRG area arising from the neuron (b1, arrow). Membrane potential trajectories are shown in a4 and b4. Scale bars, 50 μm for photomicrographs. Calibration: a4, b4, 1 sec, 10 mV.
